FEED DEVICE FOR FLASH GAS BURNERS OR LAMPS.

SPECIFICATION forming part of Letters Patent No. 748,454, dated December29, 1903.

Application filed May 11, 1903. Serial No. 156,638. (No model.)

To all whom it may concern:

Be it known that we, REGINALD WRIGHT and CHARLES J. SIDDALL, citizens ofthe United States, residing at the city of Kalama zoo, in the county ofKalamazoo and State of Michigan, have invented certain new and usefulImprovements in Feed Devices for Flash Gas Burners or Lamps, of whichthe following is a specification.

This invention relates to improvements in feed devices for flash gasburners or lamps.

The objects of this invention are, first, to provide an improved feeddevice for flash gas burners or lamps by which the gas is intermittently delivered to the burners; second, to

provide an improved automatic feed device tions of gas-pressure; fourth,to provide an improved feed device for intermittently delivering gas tothe burners which is simple, compact, and economical to produce and notliable to get out of repair. Further objects and objects relating tostructural details will definitely appear from the description tofollow.

The objects of this invention are accomplished by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure embodying the features of our invention is clearlyillustrated in the accompanying drawings, forming a part of thisspecification, in which Figure l is a verticalsectional view,taken on aline corresponding toline l l of Fig. 2, of a structure embodying thefeatures of our invention. Fig. 2 is a plan view of the structureappearing in Fig. 1. Fig. 3 is a vertical sectional view taken on a linecorresponding to line 3 3 of Fig. 2.- Fig. 4 is an enlarged detail viewtaken on a line corresponding to line 4 4 of Fig. 2. Fig. 5 is anenlarged detail view taken on a' line corresponding to line 5 5 of Fig.2. Fig. 6 is an enlarged detail view of a modification of our improvedvalve-controlling mechanism corresponding to the view shown in Fig. 5.Fig. 7 is a detail view of a gas-jetwith pilot in proximity as used in agas flash-light.

In the drawings the sectional views are taken looking in the directionof the little arrows at the ends of the section-lines, and

similar letters of reference refer to similar partsthroughout theseveral views.

Referring to the lettered parts of the drawings, the base Aispreferablyin a shell open at the top and bottom, the bottom being sealedby a plate A. A receiver A is supported upon the base A. The top of thebase A, which extends upwardly within the receiver A, is closed by adiaphragm B, of

leather or other suitable flexible material,

thus forming a receiving-chamber M below the diaphragm and a storage-chamber N above. The receiving-chamber M is conneoted to thestorage-chamber N by a pipe D, also by an auxiliary passage 0, (see Fig.2,) which is controlled by a screw-valve G.

The delivery-opening into the pipe D from the chamber M is controlled bythe valve 0. At the delivery end of the pipe D, which is gooseneck inform, so that it opens downwardly, is a valve D, which is supported uponone end of the pivoted arm F. A suitable post F is provided for thesupport of this arm. On the opposite end of the arm F is a valve E forthe delivery-pipe E of the storage -chamber N. The valve D is arrangedwithin the pipe D, (see Fig. 5,) moving downwardly to close the opening.With this arrangement the gas-pressure assists in closing the valve.

Projecting from the post F over the diaphragm B is an arm G, whichserves as a support for the rock-shaftf, which is formed into a crank J/at one end and carries the upwardly-projecting arm (1 at the oppositeend. On the end of the arm at is a counterbalanceweight d. Projectingfrom the arm d are arms 6 e, adapted to engage the ends of the pivotedarm F alternately.

The shaftfis controlled by an upwardlyprojecting standard B, carried bythe diaphragm. This standard, which is preferably of wire, is formedinto a loop at its upper end to allow the crank f of theshaftfconsiderable freedom of movement independently thereof. The freeend of the wire B is turned downwardly at b to engage a perforation inthe end 1) of the arm G, which serves as a guide therefor, so that theparts can be formed of comparatively light material. This is, in effect,a trip device, the upper and lower part of the loop serving thefunctions of arms or fingers.

In operation the gas is delivered to the receiving-chamber M by thesupply-pipe H. From the receiving-chamber M the gas is delivered intothe storage-chamber N through the pipe D, which is controlled by thevalve D on one end of the pivoted arm F. The gas is delivered from thechamber N to the delivery-pipe H by the pipe E, which is controlled bythe valve E on the other end of the arm F, so that when the valve D isclosed the valve E is open, and vice versa. The parts are so adjustedthat the valve D is closed when the apparatus is in its initialposition. The pressure of the gas in the chamber M raises the diaphragmtoits highest position, which shifts the weighted arms 6 and reversesthe position of the valves D and E, closing the delivery-pipeE of thestoragechamber N and opening the supply-pipe D. This permits the gas toflow from the receivingchamber M, and as soon as the pressure isequalized in the chambers M and N the diaphragm drops of its own weight,and through its connections the weighted arms 6 e are again shifted andthe delivery-pipe D closed and the pipe E opened. The pressure in thereceiving-chamber M again raises the diaphragm, and the operation isrepeated. The auxiliary passage 0 is adjusted to permit a small amountof gas to pass therethrough, so that the frequency of the operation ofthe device is regulated and controlled therebythat is, if aconsiderablequantity of gas passes through the auxiliary port or passage thediaphragm moves less frequently than when the greater portion is forcedthrough the delivery-pipe D. The valve 0 for the pipe D may also beadjusted, which also affects the frequency of the operation. The deviceis therefore capable of complete adjustment for all practical purposes.

In the modified structure shown in Fig. 6 a spring (1 is substituted forthe counterbalance-weight d for overcoming the dead-center and insuringa prompt and positive actionof the valves. The counterbalance-weight is,however, preferred, as the spring requires considerable carein adjusting the tension and is liable to deteriorate with use by contact withthe gas. The connection I is made to the receiving-chamber M to supplygas to the pilot of the burners. This connection could, however, be madedirectly with the supplypipe of the receiving-chamber. This forms,however, a very convenient connection for the pilot. The main burnerappears in Fig. 7 as h and the pilot as h.

We have illustrated and described our invention in the form preferred byus on account of the economy of manufacture and durability in use. Weare aware, however, that it is capable of very great variation instructural details without departing from our invention, and we desireto claim the same specifically as well as broadly.

Having thus described theinvention, what is claimed as new, and desiredto be secured by Letters Patent, is
